As I said earlier, TYPE_ATTRIBUTES is NULL here anyway, because the attributes hang in DECL_ATTRIBUTES of TYPE_DECL. And, except for config/sol2.c (which looks wrong), nothing ever calls lookup_attribute for "aligned" anyway, the user aligned stuff is encoded in TYPE_USER_ALIGN and/or DECL_USER_ALIGN and TYPE_ALIGN/DECL_ALIGN.
